2 Samuel 6:3 - Matthew Poole's English Annotations on the Holy Bible

They set the ark upon a new cart; being taught and encouraged to do so by the example of the Philistines, who did so without any token of God's displeasure upon them for so doing. But they did not sufficiently consider that God might wink at the Philistines, because they were ignorant of God's laws; and yet be angry with them for the same thing, because they knew, or might and should have known, the law of God, which commanded the priests to bear it upon their shoulders, Numbers 4:14,15 Numbers 7:9. But their present transports of joy at, the happy change of their affairs, and their greedy desire of having the ark removed, make them hasty and inconsiderate. In Gibeah; or, on the hill, as 1 Samuel 7:1. Uzzah and Ahio, the sons of Abinadab; for Abinadab himself seems now to have been dead, or at least detained at home through infirmity or indispensable occasions.
